What does NCIS stand for?
| Full form | National Criminal Intelligence Service |

| Type | Initialism |
The initialism NCIS stands for National Criminal Intelligence Service in historical UK law-enforcement references. GOV.UK describes its former intelligence-gathering and analysis role.
GOV.UK states that this role was subsequently taken over by the Serious Organised Crime Agency. Preserve the name printed in an old source rather than silently replacing it with a later organization. That statement also does not make SOCA a current service merely because it appears in the archived explanation. Intelligence is the distinguishing word here; the Norwegian NCIS uses Investigation and the US NCIS uses Naval and Investigative.

Meaning in context
- National Criminal
- The opening words in this former UK body’s name.
- Intelligence
- The key word in this expansion, distinct from Investigation and Investigative.
- Service
- The historical institutional title, rather than a present contact route inferred from an archive.
Practical examples
Keep a citation historical
- Before
An older UK publisher credit saying NCIS should be rewritten as the US agency name.
- After
Preserve National Criminal Intelligence Service and the original UK source date.
Identical initials do not authorize replacing one institution with another.
Read a role-transfer note
- Before
The archive mentions SOCA, so this proves SOCA is the current service to contact.
- After
The archived account states a later role transfer; a present service question requires current official information.
A historical relationship and a current institutional directory are different records.
Original illustrative examples, not quotations or reports of actual events.
