Frequently Asked Questions

What format should loyalty card numbers use?

Numeric formats are easiest to barcode and scan. The default pattern gives 12 digits — similar to supermarket loyalty card formats.

Can I print these numbers as barcodes?

Yes. Export the numbers to CSV, then use our Barcode Generator or pass them to a barcode library. Code 128 or EAN-13 formats work well for retail loyalty cards.

How do I prevent duplicate loyalty card numbers?

Enable 'Unique Codes Only' in the generator. For very large programmes, generate in batches and deduplicate against your existing database before issuing.
