In the Philippines, married women have the option to use their husband’s last name or retain their maiden name. Bear in mind that when a woman decides to change her last name (in her IDs, public records, etc.) she cannot undo this unless she becomes a widow or her marriage is annulled.
Here are quick guides on how you can update your government-issued IDs and other documents with your married last name.
- PhilHealth records
Bring the following at any PhilHealth office when requesting to update your records:
- PSA marriage certificate – original and photocopy
- Any government-issued ID
- SSS
Bring the following at any SSS branch to update your last name:
- PSA marriage certificate – original and photocopy
- Any government-issued ID
- Your old SSS ID
- Pag-IBIG
Bring the following at any SSS branch to update your last name:
- PSA marriage certificate – original and photocopy
- Any valid government ID
- Passport
Bring the following on your scheduled appointment at the DFA
- PSA marriage certificate
- Passport (expired or current)
- Any valid government ID
You can order your PSA marriage certificate at www.psahelpline.ph. They process and deliver PSA documents so you don’t have to line up at the PSA or take a leave from work.

will definitely still use my last name in the future for my government/valid ids
adulting life is real. these government ids are so hard to get though.
Does the government id needs to be changed with your husband surname already?
Yes, especially IDs that involve claims and benefits such as your SSS, Pag-IBIG, GSIS, and PhilHealth.
