Millions of families, businesses, and friendships span the US-Mexico border. When you need to call Mexico from the US, you want the call to connect without confusion and without a surprise bill.
Good news: the dialling format is simple. Even better: you do not have to pay what your carrier charges.
How to Dial Mexico from the US
Mexico simplified its numbering system in 2019. Mobile and landline now follow the same format:
011 + 52 + 10-digit number
- 011 is the US exit code (use + from a mobile)
- 52 is Mexico’s country code
- 10-digit number includes the area code
Example: To call 55 1234 5678, dial 011 52 55 1234 5678 or +52 55 1234 5678
The old rule requiring a “1” after the country code for mobiles was dropped in 2019. Any guide telling you to dial 011-52-1-XXX is outdated.
| Element | Value | Notes |
|---|---|---|
| Country code | 52 | Required from outside Mexico |
| US exit code | 011 | Mobiles can use + |
| Number length | 10 digits | Area code + local number |
Methods Compared
| Method | Cost | Quality | Best For |
|---|---|---|---|
| Carrier plan | $0-$3.00/min | High | Occasional callers with inclusive plans |
| Calling card | $0.01-$0.05/min + fees | Variable | Budget-conscious callers |
| VoIP app | Low per-minute or bundled | Good (needs internet) | Regular callers wanting savings |
Carrier plans work if Mexico is included. If not, per-minute rates stack up fast. Calling cards advertise low rates, but hidden fees like connection charges and expiration penalties eat your balance. VoIP apps route calls over the internet, bypassing expensive carrier networks.

Holding a virtual number from Numero gives you a local line for domestic calls. For Mexico, global calling credit is what you need.
Why it works:
