When you travel to the US and arrive at a US Port of Entry(PoE) location, you would go through the US port of entry procedures. In the past, you might have filled out an I-94 form, or sometimes, you may go through Automated Control Process (APC) Kiosks and then be interviewed by a US Customs and Border Protection(CBP) Officer.
In the past, the CBP officer may have put a stamp on your passport after a short interaction or interview. If you look closely, the stamp will have a three-letter code on the top that indicates the US port of entry location or border checkpoint of the US that you used to enter America.
Many may wonder what these US Port of Entry Abbreviations or CBP Codes are. In this article, we will understand more about the background of the CBP code, what some sample stamps with CBP codes look like, and review the complete list of CBP codes in America.
What is a CBP Code?
The US Customs and Border Protection(CBP) offices use a three-letter code representing a US Port of entry location. This three-letter code is called a CBP Code for the city. This code is mainly used for their internal communications. It is the same code that is on any of the stamps the CBP officers stamp on foreigners’ passports during their entry into the US.
For example, for the US Port of Entry city Boston, the CBP Code is BOS. For Chicago, it would be CHI. The full list of the CBP codes is in the next section.
Now, let’s look at how they are used by CBP officers when they stamp on passports and how they look.
Sample CBP Stamp put at PoE on Passport with the CBP Location Code
The image below is of the CBP port of entry stamp that was stamped in New York by a CBP Officer when the person entered the USA. The three letters “NYC” is the CBP code on the stamp that represents New York.
Below is a CBP stamp that was stamped in San Francisco. The CBP Code “SFR” in the stamp represents San Franciso.
Below is the screenshot of the CBP Stamp from Philadelphia. The CBP code is PHI.
Below is a screenshot of the CBP stamp from Houston, indicated by the CBP code HOU.
CBP Pilot program – No Physical Ink Stamps in Passport
CBP started a pilot program in August 2022 called the ‘Simplified Arrival Program’, where they no longer put in any physical ink stamp in passports when someone arrives at the US port of entry. The plan is that in the future, CBP wants to eliminate stamping passports with physical stamps.
You may not see the CBP codes stamped on the passport if such is the case. These would be captured as part of the US Travel History and users can check the I-94 Official Website
Many US PoE Locations now do not put any stamps in passports for F, M and J Students. Read CBP article and News Captured by Harvard International Office

Common FAQs
No, the electronic I-94 will not have the Port of Entry(POE) code. You cannot find out the location of entry from the I-94.
You can go to the Official I-94 website and check for the US Travel History by entering all your details. The system will give out all the details, including the Port of Entry Code and the place you entered the US. See below screenshot that lists the location, it has the POE Code. 
No, there is no implication to you or your stay in the US, if you do not have the PoE stamp or PoE code on your passport. The process now is completely electronic and it does not have any impact.
