At a glance

Here is where 1Lookup wins against OFAC Sanctions List Search, and where OFAC Sanctions List Search still wins.

Both check a name against US sanctions lists. OFAC's Sanctions List Search is the free tool from the Treasury office that issues the lists: it searches the Specially Designated Nationals (SDN) List and the Non-SDN Consolidated Sanctions List, with a match score you can slide and filters for type, program, address and ID. OFAC's own FAQ says it is meant for individual users, not for automated systems that keep running searches. 1Lookup is built for that second job: a name goes in through an API or a CSV, and a verdict comes back.

1lookupWhere 1Lookup wins

An API and a bulk CSV with a name column, where OFAC's FAQ says its web tool should not be run by automated systems
A verdict of clear, possible match or match with a recommended action, and up to ten ranked matches, where OFAC's tool returns scored rows and leaves the threshold to you
Treasury, Commerce and State lists in one pass, 12 in all, with an optional country that ranks matches without removing any
A request that is refused or cannot be answered because the lists are unreadable costs nothing and is never read as clear, on the same balance that pays for phone, email and IP checks

What it costs

From $6.00

per 1,000 sanctions screenings; $14.85 on Starter

Where OFAC Sanctions List Search wins

It is the issuing office's own search, free: OFAC administers the SDN List, and the tool searches it together with the Non-SDN Consolidated list, which holds the Foreign Sanctions Evaders List, the Sectoral Sanctions Identifications List, the correspondent account (CAPTA) list, the Non-SDN Palestinian Legislative Council List, the Non-SDN Menu-Based Sanctions List and the Non-SDN Communist Chinese Military Companies List.
Controls a screener can tune: a minimum name score slider, a type filter (Aircraft, Entity, Individual or Vessel), a program filter, and fields for address, city, state and 'ID # / Digital Currency Address'.
Fuzzy name matching explained in OFAC's own words: the score comes from the Jaro-Winkler string algorithm and the Soundex phonetic algorithm, and the FAQ says the tool 'always contains the latest versions of OFAC's sanctions lists'.
The same lists can be downloaded whole: the Sanctions List Service offers the SDN List and the Consolidated (non-SDN) List, a Customize Sanctions Dataset tool and an archive of published delta files.

What it costs

$0: the FAQ calls it 'a free tool provided by OFAC to assist the public in complying with sanctions programs'

Short answer

OFAC's Sanctions List Search is a free web tool for checking a name against the SDN List and the Non-SDN Consolidated Sanctions List, with a score slider and a program filter. OFAC says it is intended for individual users and should not be run by automated systems. 1Lookup's Sanctions Screening takes a name through an API and returns a verdict for 3 credits, about $0.015 on Starter.

What replaces what

Here is which 1Lookup product matches each OFAC Sanctions List Search job.

OFAC's tool is free and a person reads the rows it returns. This is the same kind of name check as one API call or one CSV column, ending in a verdict, billed for every completed screening, a clear one included.

Name search in the Sanctions List Search web tool (with a minimum name score)
Sanctions Screening API
A name in, with an optional two-letter country; a verdict of clear, possible match or match out, with the recommended action (approve, verify or review), up to ten ranked matches with the matched name, list, agency, programs, aliases and addresses, how many records were checked and when the lists were updated. It screens 12 US government lists, Treasury, Commerce and State, and leaves out EU, UN, UK and other lists.
3 credits per completed screening, billed for every completed screening, a clear one included

A real result

This is what one 1Lookup result looks like.

Send a name
POST a person's, company's or vessel's name of 2 to 150 characters, with a two-letter country if you have one. A name that cannot be screened, such as an empty one or one with no Latin letters, is refused with a clear error and costs nothing.
We search the 12 lists
The name is reduced to its words, so word order, accents and legal forms do not matter, and a near spelling still matches. Every record on the Treasury, Commerce and State lists that shares a word is scored, and the best matches are ranked.
Get the verdict, flat and structured
The outcome, the recommended action and the matches arrive in one JSON payload. Every completed screening bills 3 credits, a clear one included, and a name that cannot be screened bills nothing.

Questions

People ask these questions before they switch from OFAC Sanctions List Search.

What is OFAC Sanctions List Search used for?

Looking up a name on OFAC's lists. The tool uses fuzzy logic on its name field to look for potential matches on the SDN List and on the Non-SDN Consolidated Sanctions List, which holds the Foreign Sanctions Evaders List, the Sectoral Sanctions Identifications List, the correspondent account (CAPTA) list, the Non-SDN Palestinian Legislative Council List, the Non-SDN Menu-Based Sanctions List and the Non-SDN Communist Chinese Military Companies List.

How does OFAC Sanctions List Search pricing work?

It is free. OFAC's FAQ calls it a free tool provided to assist the public in complying with sanctions programs, and the pages read print no plan, quota or charge. The list files can be downloaded from OFAC's Sanctions List Service. Checked October 2026.

How much does 1Lookup charge for the same screening?

3 credits per completed screening, billed for every completed screening, a clear one included. On the Starter plan ($99 a month for 20,000 credits) a screening is about $0.015, which covers 6,666 names a month and is $14.85 per 1,000. At the Enterprise end of the rate card it is about $0.006. OFAC's tool is the cheaper bill: it is free, against $99 for a Starter month.

Can I call OFAC Sanctions List Search from my own system?

OFAC says not to. Its FAQ says the tool 'should not be utilized by automated systems that are configured to continually run searches through the tool' and points automated systems to the XML, CSV, PIP, DEL and FF list files. The pages read describe a web tool, not an API. 1Lookup is an API and a bulk CSV job, so a system can screen names as they arrive.

What does OFAC Sanctions List Search return, and what does 1Lookup add?

OFAC's tool returns scored rows, and its FAQ says OFAC 'cannot make such a recommendation' for a match threshold, so each screener sets their own and reads the rows. The score comes from the Jaro-Winkler string algorithm and the Soundex phonetic algorithm. 1Lookup returns a verdict of clear, possible match or match with a recommended action, up to ten ranked matches, and also checks the Commerce and State export-control lists, which OFAC does not administer.

Where does OFAC Sanctions List Search beat 1Lookup?

On price and on search controls. It is free and comes from the office that issues the SDN List. You can slide the minimum name score, filter by type (aircraft, entity, individual or vessel) and by program, and search by address, city, state and ID number or digital currency address. 1Lookup takes a name and an optional country only, so it cannot search by ID number or digital currency address.

How current is each source?

OFAC's FAQ says the tool always contains the latest versions of OFAC's lists and holds no historical information, so removed names are not in it. 1Lookup refreshes its copy of the lists every 6 hours and shows the update date in every answer. A repeat of the same screening by the same user within 24 hours comes from the cache at no charge.

What is the best OFAC Sanctions List Search alternative?

If you check a few names by hand and want OFAC's own search with a score slider, its tool costs nothing. If you screen names from code or a spreadsheet, and want a verdict per name across Treasury, Commerce and State lists, 1Lookup's Sanctions Screening bills 3 credits for every completed screening.

Is OFAC Sanctions List Search worth it in 2026?

Yes, for a person who checks names one at a time and wants the issuing office's own search at no cost. It is not built for automation, and it searches OFAC's lists only. If you screen names in volume, or need Commerce and State export-control lists in the same answer, compare the per-screening price of 1Lookup.
