Aztec code generator for tickets and passes
Make an Aztec code with the error correction and size you choose, full or compact, and download SVG, PDF or PNG. Checked by reading it back.
Full range has up to 32 layers, from 19 × 19 up to 151 × 151 modules.
Where Aztec is used
Airline boarding passes, rail and transit tickets, event tickets and, in some countries, vehicle registration documents. Aztec needs no quiet zone because scanners find it from the bullseye in the middle, which suits phone screens and tight ticket layouts. A small margin is still added here.
Tickets and boarding passes
Airlines and rail operators define what goes inside their codes (IATA BCBP for boarding passes, for example), and their gates check each code against their own booking systems. A code made here is not a valid ticket; use it for your own events, internal passes and tests.
Type the text, booking reference or link to encode.
Pick full or compact, the error correction and, if you need a fixed size, the number of layers.
Set the module size and download SVG, PDF or PNG. The page reads the symbol back first.
Questions
What is an Aztec code?+
A square 2D barcode with a bullseye in the middle. Scanners find the bullseye first, so Aztec needs no quiet zone and reads well from phone screens. It is used on airline boarding passes, rail and transit tickets and event tickets.
What error correction should I pick?+
23% is the usual minimum and the default here. Use 33% to 50% for codes that will be printed small, folded, or shown on cracked screens. More correction makes the symbol bigger for the same data.
Full range or compact?+
Compact Aztec has a smaller bullseye and up to 4 layers (27 × 27 modules), for short data in a small space. Full range goes up to 32 layers and about 3,000 characters.
Can I make a real boarding pass or train ticket?+
No. Airlines and rail operators set what goes inside their codes and check each one against their own systems at the gate. Use this for your own events, passes, labels and tests.
Can phones read Aztec codes?+
Many phone scanner apps and recent camera apps read Aztec, and ticket gates and handheld scanners read it reliably. For links meant for anyone, a QR code is still the safer choice.

- Boarding pass barcode (IATA BCBP)A boarding pass barcode follows IATA’s Bar Coded Boarding Pass (BCBP) standard. It encodes the passenger’s name, booking reference, flight and seat, as PDF417 on paper or Aztec or QR on phones.
- Event ticket codesEvent ticket codes are barcodes, often QR, Aztec or PDF417, that carry a unique ticket ID checked by a scanner at the door. The ID is validated so each ticket admits one person once.
- ISO/IEC 24778ISO/IEC 24778 is the international standard for the Aztec code, a 2D barcode with a bullseye finder at its center. It was first published in 2008 and defines the symbol sizes, encoding and error correction.
