What Is an Authorization Letter?
An authorization letter is a short signed letter in which one person — the principal — gives another person — the representative or authorized person — permission to act, claim a document, or transact on the principal's behalf. It is one of the most common everyday documents in the Philippines: you write one when you cannot personally appear and need a trusted person to do an errand for you, such as collecting a PSA birth certificate, claiming a parcel, or processing a clearance.
It is also known as a letter of authorization or authority letter, and in Filipino as a liham ng pahintulot or sulat ng awtorisasyon. Whatever it is called, it does the same thing: it names both people, states exactly what the representative may do, and is signed by the principal so the receiving office can rely on it.
Most authorization letters are private documents that do not need to be notarized. A signed letter, accompanied by photocopies of both parties' valid IDs, is generally enough for routine transactions. Notarization is optional and only strengthens the letter — though, as explained below, some acts require a notarized Special Power of Attorney instead.
When Do You Need an Authorization Letter?
Use an authorization letter whenever you want someone else to handle a transaction you cannot attend to in person. Common situations in the Philippines:
- Claiming civil registry documents — picking up a PSA birth, marriage, or death certificate, or a CENOMAR
- Government clearances and IDs — assisting with or claiming an NBI clearance, police clearance, or barangay document
- Agency transactions — SSS, Pag-IBIG, PhilHealth, BIR, LTO, or DFA (passport) matters
- Parcels and deliveries — claiming a package on your behalf at the courier or post office
- Utilities and accounts — handling a Meralco, water, or telecom account matter
- Records requests — requesting school records, a transcript, or medical records
- Collecting pay or documents — claiming a final salary, payroll documents, or releases
For higher-stakes acts — selling or mortgaging property, encashing a check, operating a bank account, or representing you in a legal matter — a simple letter is usually not accepted. Those require a notarized Special Power of Attorney (see the comparison below).
Required Elements of an Authorization Letter
A clear, acceptable authorization letter should contain the following:
- Date — when the letter is written
- Addressee — the office or agency the letter is for, if known (otherwise addressed "To Whom It May Concern")
- Principal's details — your full name, and ideally your address and a valid ID reference
- Representative's details — the full name of the person you are authorizing, and ideally their address and ID reference so the office can verify them
- Scope of authority — a precise statement of exactly what the representative is allowed to do (e.g., "to request and collect my PSA documents"), so the office knows the limits
- Attachments note — a line stating that photocopies of valid IDs are attached for verification
- Signature — the principal's signature over their printed name

Generate FreeHow to Write a Strong Authorization Letter
- Name both people fully. State your complete name as principal and your representative's complete name, so the office can match each to a valid ID.
- Be specific about the task. Spell out exactly what the representative may do — "to request and collect my PSA birth certificate," not just "to transact for me." A narrow, precise scope is easier for an office to accept and protects you from misuse.
- Address it correctly. If you know the office, name it; otherwise "To Whom It May Concern" is fine. A correctly addressed letter moves faster at the counter.
- Attach the IDs. Include photocopies of your valid government ID and your representative's ID. Your representative should also bring the original of their own ID.
- Sign it yourself. The principal must sign over their printed name. An unsigned letter will not be honored.
- Check the office's rules first. Some transactions need the principal to appear in person, and some need a notarized SPA. Confirm the current requirement before sending your representative so the trip is not wasted.
Authorization Letter vs. Special Power of Attorney
These are often confused, but they are not interchangeable. An authorization letter is a simple, usually un-notarized letter that works well for routine, low-risk errands — claiming documents, picking up parcels, requesting records. A Special Power of Attorney (SPA) is a formal, notarized document that the law requires for significant legal acts: selling or mortgaging real property, encashing checks, operating a bank account, entering into contracts, or representing you in court or a legal matter. For those acts, offices and banks will generally refuse a plain letter and ask for an SPA. When in doubt about a financial or property transaction, prepare an SPA rather than a letter.
When an Authorization Letter Is Not Enough
Two situations commonly trip people up. First, in-person requirements: many government processes — NBI and police clearances, passport applications, several LTO, SSS, and visa transactions — need the principal to appear for biometrics, a photo, or an interview, so a representative can only assist or claim the finished document. Second, acts that require an SPA: property dealings, bank account operations, and check encashment usually need a notarized Special Power of Attorney, not a letter. In both cases, confirm the exact requirement with the office or bank beforehand.
