What is the emergency number in the USA?

The emergency number in the USA is 911 – for police, fire and ambulance. Give the location of the emergency first, ideally with a street address.

Can I text 911 from a SIM card from home?

You should not rely on it. Text-to-911 is only available in certain areas, and Washington State points out explicitly that it does not work while roaming. Call 911 whenever you can.

What should I do if I lose my passport in the USA?

Report the loss to your country's embassy or consulate and to the police, and apply for a replacement Form I-94 if necessary. With a new passport, you will need a new ESTA for future trips.

Emergencies in the USA: 911 and Other Important Numbers

The most important number first: 911 reaches police, fire and ambulance services — call rather than send a text. With a foreign SIM card on roaming, text-to-911 does not work in many places. Below are all the key emergency numbers and what to do if you lose your passport.

911: the emergency number for police, fire and ambulance

An emergency is any situation in which you need immediate help from the police, fire service or an ambulance. In that case:

Dial 911 immediately
Give the location of the emergency first, ideally with a street address
Stay on the line and answer the dispatcher’s questions

Call rather than text: Text-to-911 is only available in certain areas. Washington State points out explicitly that texting 911 does not work while roamingand is only available in English. The rule is: “Call if you can; text if you can't.” Availability differs by state and region.

Older 3G phones and some 4G devices without VoLTE cannot make calls in the USA — not even to 911. The US regulator, the FCC, advises international visitors to check this before they travel.

Other important numbers

988 — Suicide & Crisis Lifeline: call, text or chat with trained counsellors, 24 hours a day, free and confidential
1-800-222-1222 — Poison Help: if you suspect poisoning, call this number straight away; it connects you to your local poison centre
Life-threatening situation: always call 911 first

Lost or stolen passport

According to the official USA.gov portal, you should take the following steps:

Report the loss or theft to your country’s embassy or consulate
Report the loss to the police
If necessary, apply for a replacement Form I-94

New passport = new ESTA: your ESTA authorisation is linked to your passport. If you are issued a new passport, you will need a new ESTA for future trips to the USA.
