Every molecular model ([[Atomic coordinate file|atomic coordinate file]]) in the [[Protein Data Bank]] (PDB) has a unique accession or identification code. These codes are always 4 characters in length. The first character is a numeral in the range 1-9, while the last three characters can be either numerals (in the range 0-9) or letters (in the range A-Z in [http://en.wikipedia.org/wiki/Latin_alphabet#Classical_Latin_alphabet Latin alphabet]). Plans for an expanded identification code system that handle more entries [[#Future Plans for Expanded PDB Codes|have been announced]]. | Every molecular model ([[Atomic coordinate file|atomic coordinate file]]) in the [[Protein Data Bank]] (PDB) has a unique accession or identification code.
