Comprender los códigos de área

To ensure a continuing supply of telephone numbers, the North Carolina Public Utilities Commission has approved an all-services overlay for the 910 area code region, which serves communities such as Fayetteville, Fort Bragg, Jacksonville, Lumberton, and Wilmington, within the counties of Cumberland, Onslow, Robeson, and New Hanover. The new 472 area code will serve the same geographic area currently served by the 910 area code.

What is an Area Code Overlay?

Un ajuste es la incorporación de otro código de área (472) dentro de la misma área geográfica como un código de área actual (910). The overlay does not require you to change your existing area code or phone number, or how you dial your calls. You will continue to dial the area code and phone number for all local calls, as you do today, within and between the 910 and 472 area codes.

Who is affected and when does the new 472 area code become effective?

Beginning October 7, 2022, customers in the 910 area code region may be assigned a number in the new 472 area code when they request new service or an additional line. Customers receiving a 472 area code will be required to dial the area code and phone number for all local calls, just as customers with phone numbers from the 910 area code do today.

¿Qué es lo que tendrás que hacer?

Customers in the overlay region should:

• Continue to dial 10 digits (or 1+10 digits) for all local calls, including calls within the same area code.
• Continue to identify your telephone number as a 10-digit number, and include the area code when giving the number to friends, family, business associates, customers, etc.
• Ensure that all services, automatic dialing equipment, or other types of equipment recognize the new 472 area code as a valid area code and continue to store or program telephone numbers as 10-digit numbers. Some examples are: stored phone numbers in contact lists in wireless or cordless phones, PBXs, fax machines, Internet dial-up numbers, speed dialers, call forwarding settings, voicemail services, medical alert devices, safety alarm security systems and gates, ankle monitors and or other similar equipment.
• Check items such as your website, personal and business stationery and printed checks, advertising materials, contact information, and your personal or pet ID tags to ensure the area code is included.

¿Qué es lo que quedará igual?

• Tu número de teléfono, incluso el código de área actual no cambiará.
• El precio de una llamada, área de cobertura y otras tarifas y servicios no cambiarán por la superposición de código.
• What is a local call now will remain a local call.
• You will continue to dial 10 digits or 1+10 digits for local calls within and between the overlay area codes, and 1+10 digits for long distance calls.
• You can still dial just three digits to reach 911, as well as 211, 311, 411, 511, 611, 711 or 811 if those are currently available in your community.

Beginning November 9, 2021, new telephone lines or services may be assigned numbers with the new 771 area code. If you have a 771 area code, you must dial the area code + telephone number or the call will not complete.

¿Qué es lo que tendrás que hacer?
In addition to dialing the area code + telephone number for all local calls, all services, automatic dialing equipment, or other types of equipment that are programmed to dial a 7-digit number will need to be reprogrammed to include the area code. Some examples are life safety systems and medical monitoring devices, fire or burglar alarm and security systems or gates, PBXs, fax machines, Internet dial-up numbers, speed dialers, call forwarding settings, voicemail services and similar functions, etc. You may also want to check your websites, personal and business stationery and checks, advertising materials, personal and pet ID tags and other such items to ensure the area code is included.

¿Qué es lo que quedará igual?

• Tu número de teléfono, incluso el código de área actual no cambiará.
• El precio de una llamada, área de cobertura y otras tarifas y servicios no cambiarán por la superposición de código.
• Lo que ahora es una llamada local seguirá siendo una llamada local, independientemente de la cantidad de dígitos marcados.
• Aún puedes marcar solo tres dígitos para el 911, así como 211, 311, 411, 511, 611, 711 y 811.

Para garantizar un suministro permanente de números telefónicos, la Comisión de Servicios Públicos de California (CPUC) ha aprobado la adición del código de área 840 al área geográfica que cubre el código de área 909. A este proceso se lo conoce como una superposición de código de área. Dicha superposición de código requerirá que todas las llamadas se completen llevando a cabo nuevos procedimientos de marcado.

¿Qué es el ajuste de código de área?

Un ajuste de código de área es la adición de otro código de área (840) a la misma región geográfica, que utiliza un código de área existente (909). Un ajuste no requiere que los clientes cambien su código de área actual, pero sí requiere utilizar un nuevo procedimiento de marcado para completar las llamadas telefónicas. Cuando se implementa una superposición de código, los clientes con línea telefónica fija deben marcar "1" seguido del código de área y del número de teléfono de siete dígitos para completar todas las llamadas, incluidas aquellas hechas dentro del mismo código de área. Los clientes del servicio móvil deben ingresar el código de área y el número de teléfono de siete dígitos o 1 + el código de área y el número de teléfono de siete dígitos para poder completar todas las llamadas, incluidas aquellas dentro del mismo código de área.

¿Quiénes se ven afectados?

Se verán afectados todos los clientes que tengan un número de teléfono con el código de área 909 ó 840. El código de área 909 cubre la porción del sudoeste del condado de San Bernardino, la porción del este del condado de Los Ángeles y pequeñas porciones de los condados de Orange y Riverside. El código de área 909 cubre las ciudades de Big Bear Lake, Calimesa, Chino, Chino Hills, Claremont, Colton, Diamond Bar, Eastvale, Fontana, Grand Terrace, Highland, Industry, La Verne, Loma Linda, Montclair, Ontario, Pomona, Rancho Cucamonga, Redlands, Rialto, San Bernardino, San Dimas, Upland, Walnut y Yucaipa. El nuevo código de área 840 se utilizará en la misma área geográfica que actualmente usa el código de área 909.

What will be the new dialing procedures?

Para completar llamadas desde un teléfono de línea fija, el nuevo procedimiento de marcado exige que todas las personas con código de área 909 ó 840 marquen 1 + código de área + número de teléfono. Esto significa que las llamadas en los códigos de área 909 o 840 que actualmente se hacen marcando siete dígitos, deberán hacerse marcando 1 + código de área + número de teléfono.

To complete calls from a wireless phone, callers must dial the area code + telephone number or 1 + area code + telephone number whenever placing a call from a phone number with the 909 or 840 area code.

¿Cuándo comenzará el cambio en el marcado?

A partir del 25 de julio de 2020, debes comenzar a llevar a cabo los nuevos procedimientos de marcado al realizar una llamada desde los códigos de área 909 ó 840. Si te olvidas y sólo marcas siete dígitos, tu llamada se realizará de todas formas.

A partir del 23 de enero de 2021, debes implementar los nuevos procedimientos de marcado, tal como se describen anteriormente, para todas las llamadas. Después de esta fecha, si no llevas a cabo los nuevos procedimientos, tus llamadas no podrán completarse y una grabación te indicará que cuelgues y marques nuevamente incluyendo el código de área.

A partir del 23 de febrero de 2021, es posible que a las nuevas líneas o servicios telefónicos del área 909 se les asignen números con el nuevo código de área 840. Cualquiera que reciba un número de teléfono con el código de área 840 debe realizar los nuevos procedimientos que se describen anteriormente.

¿Qué es lo que tendrás que hacer?

Además de que cambian los procedimientos de marcado, todos los servicios, equipos de marcado automático u otras clases de equipos que están programados para marcar un número de siete dígitos deberán ser reprogramados para que se puedan usar con el nuevo procedimiento de marcado. Algunos ejemplos son los dispositivos del sistema de seguridad de vida y los dispositivos de monitoreo médico, PBX, máquinas de fax, números de Internet dial-up, sistemas de alarma y seguridad y compuertas, marcadores rápidos, configuraciones de transferencia de llamadas, servicios de correo de voz y otros servicios o equipos similares. También tendrás que revisar tus artículos de escritorio y cheques personales y comerciales, materiales publicitarios, sitios web, información de contacto y etiquetas de identificación personal o de mascotas para asegurarte de que el código de área esté incluido en el número de teléfono.

¿Qué es lo que quedará igual?

• Tu número de teléfono, incluyendo el código de área actual, no cambiará
• El precio de una llamada, el área de cobertura, u otras tarifas y servicios no cambiarán debido al ajuste
• Lo que ahora es una llamada local seguirá siendo una llamada local, independientemente de la cantidad de dígitos marcados
• Igualmente puedes marcar sólo tres dígitos para comunicarte con el 911, como también con el 211, 311, 411, 511, 611, 711 y 811

On February 27, 2020, the Public Utility Commission of Texas approved an additional all services overlay as the relief method for the existing 214/469/972 area code overlay to ensure a continuing supply of telephone numbers. The new 945 area code will be superimposed over the region now served by the 214, 469 and 972 area codes.

¿Qué es el ajuste de código de área?

This overlay is the addition of another area code (945) to the same geographic region as existing area codes (214/469/972). Este ajuste no requiere que los clientes cambien su código de área o número telefónico actual ni que modifiquen el marcado de sus llamadas. 

¿Quiénes se verán afectados y cuándo comenzará el cambio?

Beginning January 15, 2021, customers in the metropolitan area of Dallas and surrounding communities such as Allen, Frisco, Grand Prairie, McKinney, Rockwall, Terrell, and Waxahachie, may be assigned a phone number in the new 945 area code when requesting new service, an additional line, or in some cases, moving their service. The 945 area code will co-exist everywhere in this region with the 214, 469 and 972 area codes.

¿Qué será necesario que hagan los clientes?

Customers served by the 214, 469 and 972 area codes overlay should:

• Continuar marcando 10 dígitos para todas las llamadas locales dentro de la región correspondiente al ajuste.
• Continuar identificando sus números telefónicos con 10 dígitos e incluir el código de área al brindar sus números a amigos, familiares, socios comerciales, clientes, etc.
• Asegurarse de que todos los servicios, equipos de marcado automático u otros tipos de equipos reconozcan el nuevo código de área 945 como código de área válido, y seguir programando los números telefónicos con 10 dígitos. Algunos ejemplos incluyen: números de teléfonos guardados en las listas de contactos de teléfonos móviles e inalámbricos, PBX, faxes, números de Internet dial-up, dispositivos de marcado rápido, configuraciones de transferencia de llamadas, servicios de correo de voz, dispositivos de alerta médica, sistemas y compuertas de seguridad y alarma, monitores de tobillo u otros equipos similares.
• Revisar sus sitios web, artículos de oficina, materiales publicitarios, cheques personales y comerciales, información de contacto y etiquetas de identificación personal o de mascotas, para asegurarse de que el código de área esté incluido.  

¿Qué es lo que quedará igual?

• No cambiarán los números telefónicos de los clientes, incluido el actual código de área.
• El precio de una llamada, área de cobertura y otras tarifas y servicios no cambiarán por la superposición de código.
• Lo que ahora es una llamada local seguirá siendo una llamada local, independientemente de la cantidad de dígitos marcados.
• Customers in the overlay region will continue to dial 10 digits for local calls within and between the overlay area codes, 1+10 digits for long distance calls, and 0+10 digits for operator-assisted calls.
• Los clientes pueden seguir marcando sólo tres dígitos para comunicarse con el 911, como también con el 211, 311, 411, 511, 611, 711 o 811, en caso de que estos estén actualmente disponibles en sus áreas.
