New format for list numbers

New format for list numbers

As part of the European Chemicals Agency (ECHA) weekly news update it was announced that there will be a new format for list numbers. Each substance registered or notified under REACH [Regulation (EC) No 1907/2006] or CLP [Regulation (EC) No 1272/2008] needs an identifier. If a substance is not identified by an EC number and has not been previously notified or registered, REACH-IT assigns a new list number to that substance.

ECHA are hoping to update the list number format around early summer 2025 as numbers in the current format are soon running out. The new format will keep the current length but will change from numeric to alphanumeric.

Example of the current format: 100-000-1

Example of the new format: A00-001-5

Companies may need to take action to adapt their recording systems outside REACH-IT to accommodate the new format. List numbers assigned before the format change will not be affected.
