Dialing sequence, step by step
- 1
Start with + on a mobile, or 00 CC when the Brazil network requires an all-digit access prefix.
- 2
Add 1, the country calling code for United States.
- 3
Add the destination national significant number. There is no separate domestic trunk digit to remove. The digit 1 may be used before the ten-digit number for long-distance dialling, but it is also the shared country code in international notation.
CC represents the selected two-digit Brazilian carrier code. The carrier code belongs to this call's access string, not to the stored +1 destination number.
Mobile and landline examples
X means a subscriber digit placeholder, so these patterns explain the transformation without publishing a private callable number. Save the + format; use the access-prefix format only for a call that starts in Brazil.
| Number type | Domestic in United States | Save on mobile | Dial from Brazil |
|---|---|---|---|
| Mobile | (202) 555-01XX | +1 202 555 01XX | 00 CC 1 202 555 01XX |
| Landline | (212) 555-01XX | +1 212 555 01XX | 00 CC 1 212 555 01XX |
How the international format is built
Portable contact format
+ 1 + national significant number
The + represents international access. It is display notation, not one of the E.164 digits.
Digits-only call from Brazil
00 CC + 1 + national significant number
The first part routes out of the origin network and must not be stored as part of the destination.
E.164 limits the full international number to 15 digits and excludes international and national prefixes. See the E.164 and international-format guide for the reusable structure and regional exceptions.
Common mistakes for this route
- Dialling 00 without the Brazilian carrier-selection code where the originating service requires one.
- Saving the selected carrier code inside the +1 destination contact.
