Can I paste a full Japanese address to make the barcode?

No. This page encodes prepared data, not a written address. For example, postcode 100-0013 and extracted address number 1-3-2-503 become 10000131-3-2-503. The tool does not look up postcodes, verify delivery addresses or create a paid shipping label.

What should I check before mailing?

Check the prepared address data, bar dimensions, spacing and placement against Japan Post’s printing specifications. Print at the intended size without stretching. A PNG or SVG preview is not postal approval; have Japan Post check a sample when required.

Using Japan Post Customer Barcode

This postal barcode helps Japan Post sort mail by destination; it is not a parcel-tracking code. Prepare the address-number part using Japan Post’s extraction rules. The format has room for 20 encoded positions, with each letter using two, so the limit is not simply 20 typed characters.
