Describes the representation of ID-tags as a 62-position bar-no-bar code (BNB-62) printed in fluorescent ink in area R1 on the reverse side of items.

This part of the Technical Specification defines the representation of ID-tags as a 62-position bar-no-bar code (BNB-62) printed in fluorescent ink in area R1 on the reverse side of items. BNB-62 encoding is one of two encoding specifications supported by this Technical Specification ) for the printing of ID-tags in area R1, the other being BNB-78, which is specified in CEN/TS 15844-2. NOTE 1 Representation in the form of a 4-state code printed on the front of the item is covered in CEN/TS 15844-4 for flats and CEN/TS 15844-5 for small letters. BNB-62 encoding is authorised for use only by three issuers: An Post (Ireland), Canada Post and USPS. It should be encountered, on incoming items, only on mail items which originated in Canada, Ireland or the United States. Other issuers wishing to apply ID-tags in area R1 are required to use the BNB-78 encoding defined in CEN/TS 15844-2. NOTE 2 ID-tags encoded in area R1 are required by article RL 123 of the UPU Letter Post Regulations [2] to be compliant with UPU standard S18 - and by this with the related CEN/TS 15844. This supports only two encodings in area R1, namely BNB-78 as defined in CEN/TS 15844-2 and BNB-62 as defined herein. The latter is authorised for continued use only by the three issuers mentioned above. Where ID-tags are used, and are applied in area R1 on the reverse side of letter mail items of size up to and including C5, the use of BNB-78 encoding is mandatory for all other issuers. NOTE 3 BNB-62 encoding is not considered suitable for use on flats. CEN/TS 15844-4 defines a 4-state encoding which may be used for this purpose.
