OFAC SDNTK sanctions program

SDNTK is one of the program codes OFAC attaches to entries on the Specially Designated Nationals list. As of 2026-07-24 it appears on 1,400 SDN entries. Designations under this program are made under Foreign Narcotics Kingpin Designation Act, Executive Order 14059 (Illicit Drugs) and Executive Order 13224 (Terrorism).

What the SDNTK code means on an SDN entry

OFAC does not maintain one list per sanctions program. It maintains one SDN list, and tags each entry with the program or programs it was designated under. An entry can carry several: of the 1,400 entries tagged SDNTK, 31 also carry at least one other program code.

The legal authorities OFAC records against these designations are:

• Foreign Narcotics Kingpin Designation Act
• Executive Order 14059 (Illicit Drugs)
• Executive Order 13224 (Terrorism)
• INA
• Executive Order 12947 (Terrorism)
• Executive Order 13581 (TCO)

That matters for screening: if you filter an SDN extract to a single program code you will silently drop entries that were designated under a different code but are blocked all the same. Screen the whole list, then use the program code to explain a hit — not to decide which entries to load.

SDNTK designations by type

When SDNTK designations were made

The earliest entry still carrying this code was published 1997-10-08; the most recent was 2021-10-06. Designations per year, most recent first:

Countries recorded against SDNTK entries

Counted from the address, nationality and citizenship fields on each entry. An entry can record more than one country, and many record none, so these do not sum to the entry count:

Most recent SDNTK designations

Names are reproduced exactly as OFAC publishes them. OFAC also publishes alternate identities (a.k.a. spellings and transliterations) for many entries, and a screening system that matches only the primary name will miss them.

Digital-currency addresses under SDNTK

OFAC publishes 12 digital-currency addresses on entries carrying this program code. Those are broken out by chain on the sanctioned address pages.

Screen this programmatically

The same data behind this page is available as a single unauthenticated GET. It checks a counterparty name against all SDN primary names and alternate identities, and returns a match list rather than a yes/no so you can log what matched and why:

The free tier allows 5 checks per day with no signup, which is enough to wire the call up and see the response shape. Production limits and the audit log are on the paid tiers; the API reference covers batch screening and the degraded flag you should alert on.
