The bio page of a passport is the densest identity document most people own - number, date and place of birth, parents' names, and the machine-readable zone along the bottom that repeats all of it in one scannable line. Travel agents, visa consultants, and hotels routinely ask for a copy. Mask the number and the MRZ strip, and what's left still confirms who you are.
When to use this
Use when: sending a passport copy to a travel agent or visa consultancy, emailing it to a hotel for check-in, sharing it with an employer for an offer-stage background check, attaching it to a forex or bank form.
Frequently Asked Questions
Don't forget the machine-readable zone - does the tool handle it?
The two lines of characters at the bottom of the bio page repeat your passport number, date of birth, and nationality in a format any scanner app can read in a second. Masking the printed number but leaving the MRZ visible achieves nothing. Draw a second rectangle across both MRZ lines - the tool supports as many masks per page as you need.
Is it legal to send a partially masked passport copy?
For private parties - hotels, agents, employers - yes, and it's the safer default. Official processes are different: visa applications, immigration, and bank KYC under PMLA generally require the unmasked bio page, and a masked copy will be rejected. Mask for convenience-level sharing, not for statutory submissions.
