Frequently asked questions
Are long numeric values preserved?
Yes. Input is handled as text, so leading zeroes are preserved.
Can I encode Hindi or emoji?
Not with this Code128 subset B tool. Use the QR generator for Unicode text.
Is this a retail product barcode?
This creates a generic Code128 symbol, not an assigned retail identifier or GS1 label. Confirm the required barcode format with the receiving system.
