Number transfer guide

If you have no commitments, or notice period with the provider you are leaving, we will transfer your number within four business days.

Day 1
We receive your request for a number transfer and the ČVOP number. We'll send the order for a number transfer to the operator you are leaving.
Day 2
The operator you are leaving confirms the ČVOP number and releases your phone number for transfer.
Day 3
The number is recorded in the central database of transferred numbers.
Day 4
Your number is active on O2.


While the number is being transferred, your SIM card might be temporarily unavailable.

Detailed information about transferring numbers can be found in the general terms and conditions for customers with a postpaid tariff, and for customers with a prepaid card.

What is a ČVOP number?

This is a 14-digit number that serves as a transfer authorization code. ČVOP is an abbreviation for a notice number from the operator you are leaving. This number is always generated by the operator you are leaving. It is valid for 60 days from the date it was generated.
