Production Codes is an alphanumeric designation used to uniquely identify episodes. Each episode has its on unique number but does not always follow the order of the previous production code. EastEnders has been designated a programme number 50.
To understand the the elements of a production code, it needs to be broken into four sections.
If we us the first episode as an example - LDL G 100K
- LDL - This indicates its a London Drama Serial.
- G - Indicates the year of costing.
- 100 - The organiser's label.
- K - The check code for the label.

- Production codes always change in the month of April due to the financial year running from 1 April and ending 31 March of the next calendar year.
- Hour-long Episodes are alway split into two half-hour episode for re-sale by BBC Worldwide so that they can be sold abroad. An example of this is Episode 4990 (2 January 2015) was given the production code "DRA D222D" but was split into two episode with the production codes "DRA D220P and DRA D221J".
- Episodes after Episode 194 but before Episode 3770 will show as an incorrect episode number as episode numbers in the early years were not continuous and were reset, when an additional episode was added in 1994, 2001 and 2009. It was not until April 2009 that the BBC retroactively renumbered episode numbers to give consecutive numbering across the series.
