Required Documents

• ☐ CVP (Portability Validation Code) — Migration code obtained from your current provider before initiating the port
• ☐ Latest Invoice — Copy of the most recent invoice from your current provider
• ☐ Authorized Person ID — Passport or national identification document copy

Porting Timeline

Restrictions & Special Conditions

• The LoA must be signed with a wet signature (handwritten, not digital).
• The address on the LoA must be a local address within the same city as the number prefix being ported.
• The CVP (Portability Validation Code) must be obtained from the current provider prior to submitting the port request. This is a mandatory migration code.
• Numbers with associated services (mainline numbers) cannot be ported, as the porting process cancels those services.

Key Definitions

• CVP (Portability Validation Code) — A migration code issued by the current (losing) carrier that authorizes the port-out of the number. Must be obtained before submitting the porting request.
• Wet Signature — A physical, handwritten signature on the document (as opposed to a digital or electronic signature).

Notes

• Portugal requires more documentation than many other countries, including both a CVP code and a Power of Attorney.
• Ensure the address on all documents matches the city/area of the number prefix to avoid rejection.
