Blank margin around the code required by the standard. Keep it on.

Share of the code used for error correction. A higher level gives a bigger code.

What is Aztec

Aztec has a bullseye pattern in the middle that scanners use to find the code. It therefore needs no quiet zone and reads well from a phone screen.

The error correction level is the share of the symbol used for correction. The standard recommends 23%; a higher level adds robustness and size.

Frequently asked questions

Where is Aztec used?

Mainly on tickets: rail tickets, airline boarding passes and public transport tickets, especially shown on a phone.

Does Aztec need a margin?

It needs no quiet zone, but the generator leaves one module of space so the code does not blend into its surroundings.

Can a phone read Aztec?

Most barcode apps read it, but not every built-in camera.

Which error correction level should I choose?

The recommended 23% is enough for codes shown on a screen. Choose a higher level for printed codes that may get damaged.

Aztec or QR?

For tickets and uses where a carrier requires it, choose Aztec. For links and content for customers, QR, which everyone knows, is usually better.
