  • Please make sure you provide information that exactly matches what is on record with the provider you currently use.
  • A letter of agreement must be handwritten with a wet signature and dated within the past three months. Most LATAM countries do not accept LOAs that are electronically signed.
  • On the LOA, the losing provider’s name should be listed.
  • After the order has been submitted, it will only be possible to carry out number portability checks. If you are losing a provider, you may be advised that your number will not be ported.
  • While the number ports away from the provider who had previously been your service provider, you may experience some loss of service as incoming calls while the number transfers from the provider who lost your service.

The only numbers that can be ported are those of Movistar.


In order to qualify for this position, the following documents must be completed and submitted:

  • Designation documents (documentos de constitución) or notarized powers of attorney must be notarized. The Mexican Telecommunications Regulatory Authority requires this. Notarization is 100% mandatory. In most cases, the constitution should be used.
  • Identification documents valid (for example, passports or national IDs) by the signer of the notarized designation document or notarized power of attorney document. Employees from Mexico should provide identification.
  • The letter must include the local address (if not in the United States). English and Spanish examples are available.

Additional notes:

  • When you pay a third-party US reseller for your services instead of a Mexican Telco, you should follow the following steps:
    • A third party’s POA and their respective ID will need to be included in the documents as well as the third party’s signature.
    • If the third party does not approve the port within the 24-hour period, then the port will need to be resubmitted.
    • You must submit ALL documents with the same signature (the name on the ID must match the signature on the document).


Documentation required:

  • DNI (National Identification Document) of the LOA signer.
  • A copy of the Purchase Document/Proof of the Signer. A copy of this can serve as a type of incorporation document. In this way, it can prove that the organization’s signatory has the authority to act on its behalf. It is imperative that the document be properly signed in wet ink. Electronic signatures are not acceptable.
  • Copy of the latest bill from the current local service provider.

After a porting date has been specified, the porting process will be completed in a working time frame of 6 hours (maximum downtime of 3 hours). If possible, it would be advisable to avoid scheduling the porting on a Friday or a holiday.
