Fill an authorization letter online — free, in your browser
An authorization letter is a short, informal note that lets another person act on your behalf for one specific task — picking up your passport or transcripts, collecting a package or a check, or handling a single transaction when you can't be there yourself. AttachKit opens a clean fillable template and fills it right in your browser: your name, address, phone, and email auto-fill from a saved profile using on-device heuristics, and you complete the authorized person's details, the exact authority you're granting, and the dates. This is not a power of attorney or a grant of legal agency — for formal or ongoing authority, use a power of attorney instead. Your PDF never leaves your device.

Authorization letter questions, answered
- Is an authorization letter the same as a power of attorney?
- No. This is an informal letter authorizing one specific task, like picking up documents or collecting a package. A power of attorney is a formal legal instrument granting broader or ongoing authority (financial, medical, or general). For anything formal or ongoing, use a power of attorney instead of this letter.
- What should I include so the letter is accepted?
- Name the person you're authorizing, describe the exact task in plain, specific terms, list the organization or place it applies to, and give a valid-from and valid-until date. Many offices also want the authorized person to show ID, so note their ID type and number and keep your contact details on the letter so the receiver can confirm with you.
- Does the letter need to be notarized?
- Usually not for informal, everyday tasks. Some organizations set their own rules and may ask for a signature, a photocopy of your ID, or notarization before they'll release documents or funds. Check with the specific office or business that will receive the letter, since requirements vary by organization and state.
- Does the authorized person sign too?
- No. As the person granting authorization, you sign and date the letter. The authorized person typically presents it along with their own ID when they carry out the task; the receiving party may verify the authorization with you directly using the contact details you provided.
