How to Apply for a PESEL Number?
There are two main ways to obtain a PESEL number:
1. Automatically Through Address Registration
If you register your residence (zameldowanie) at your local city office, you will automatically receive a PESEL number.
You must visit your local municipal office (Urząd Miasta or Gmina office).
2. By Submitting an Application
If you cannot register your address, you can apply separately by submitting a PESEL application form.
You must:
-
Visit your local municipal office

Provide a valid passport
-
Provide residence documents (visa, residence card, or work permit)
-
State a legal reason for needing a PESEL number
There is usually no fee for issuing a PESEL number.
Where Do You Apply?
You apply at your local city or municipal office in your place of residence.
For example:
-
If you live in Warsaw, you apply at the Warsaw City Office.
-
If you live in Kraków, you apply at the local municipal office there.
Processing is often done on the same day.
How Long Does It Take?
In most cases:
-
If applying with address registration – you receive it immediately.
-
If applying separately – it may take a few days.
Always keep a printed confirmation for your records.
What Is the Difference Between PESEL and NIP?
Many foreigners confuse PESEL with NIP.
-
PESEL – Personal identification number for individuals.
-
NIP – Tax identification number, mainly used by businesses.
Today, most individuals in Poland use only PESEL for tax purposes.
Can You Work in Poland Without PESEL?
Technically, it may be possible for a short time. However:
-
Employers require it for official payroll.
-
Social security registration requires it.
-
Tax filing requires it.
So in practice, you should obtain your PESEL number as soon as possible.
Is PESEL the Same as a Residence Permit?
No.
A PESEL number:
-
Is an identification number only.
A residence permit:
-
Is a legal document allowing you to stay in Poland.
They are separate but often connected in administrative processes.
What Happens If You Lose Your PESEL?
You do not “lose” a PESEL number because it is permanently assigned to you.
If you forget it:

Request confirmation
Your PESEL remains valid for life.
