Local and International Calling Instructions

• Local calls within Ciudad del Carmen: If you are calling from another number within the same area code, you may dial only the seven-digit local number (XXX XXXX). However, due to number portability and the possibility of overlay plans, it is always safe to dial the full national format.
• National calls from other area codes in Mexico: Dial 01 938 XXX XXXX. The '01' prefix is required for long-distance calls within Mexico.
• International calls from abroad: Dial your country's exit code (e.g., 011 from the US/Canada), followed by 52 (Mexico's country code), then 938, and the seven-digit local number. Example: +52 938 123 4567.

Regulatory and Technical Notes

As a geographic number, the 938 code is tied to the PSTN (Public Switched Telephone Network) and is used by both fixed-line operators and, in some cases, VoIP providers that offer local presence. The Federal Telecommunications Institute (IFT) oversees numbering assignments in Mexico, ensuring that geographic codes remain associated with specific regions. However, with the advent of number portability, a number with the 938 prefix may be routed to a mobile or VoIP service, but the geographic association remains for billing and emergency services purposes.

For businesses, having a local 938 number establishes a presence in Ciudad del Carmen, which is particularly valuable for companies serving the oil, gas, and maritime industries. When dialing from abroad, always verify the current dialing procedures with your carrier, as some countries require different exit codes.
