A TINL is a TINP assigned either by tango.info, then called TINO or by a tango.info-authorised party, then called TINC, for the for the purpose of identifiying an item having no known GTIN (e.g. a music album having no barcode).
TINL is disjunct from TING/GTIN.
TINLs are in the GTIN range 0200 - 0299, defined by the GTIN standards organisation GS1 as Restricted distribution (GS1 MO defined) where MO means [national] member organisation. tango.info considers this range to be acceptable for use in TINP because the GTIN authority has designated them 'not for international use'. Currently the only GS1 numbers used by tango.info are in the 0248000 range.
For a list containing many tango.info-assigned TINLs, see https://tango.info/?q=0248000. This search matches the embedded term, so may contain some false positives. It is not known if this list contains all tango.info-assigned TINLs. As of 2008-03-29 it contains no TINLs assigned by other parties, i.e. it only contains TINO.
TINC and code agreements
A code agreement is the designation by tango.info of a range of TINLs for assignment to GTIN-less items by a particular third party. For details see TINC.
