ESTA for Taiwanese Citizens: The National ID Number Rule and Other 2026 Essentials

Does Taiwan qualify for ESTA? Yes — with one Taiwan-only condition

Taiwan has been a member of the US Visa Waiver Program (VWP) since November 2012, so Taiwanese travellers can visit the United States for up to 90 days for tourism, business or transit without a visa — using an approved ESTA instead. ESTA is not a visa: it is an online pre-screening linked electronically to your passport, with no embassy visit and no interview (the basics are in our guide to what ESTA is). But Taiwan's VWP terms include a condition that applies to no other member: it is not enough to hold a Taiwan passport. You need a biometric e-passport that contains your National ID number — the personal identification number tied to your household registration. That detail is the single most common Taiwan-specific stumbling block, so let's start there.

The National ID number rule — the top Taiwan-specific gotcha

The US designation covers Taiwan passport holders with unrestricted right of permanent abode in Taiwan — in practice, people with household registration, whose National ID number is printed on the passport's biodata page. Per the American Institute in Taiwan, eligible travellers hold a biometric Taiwan e-passport issued on or after 29 December 2008 that contains a National ID number. Two practical consequences:

• Check the biodata page before you apply. If the personal ID number is there, you can use ESTA. Virtually all passports issued to residents with household registration have it.
• The ESTA form will ask for it. Where the application requests a personal identification number and a national identification number, AIT's guidance is to enter your Taiwan National ID number for both. Leaving it blank or mistyping it is a classic cause of avoidable problems.

If your passport does not show a National ID number — typically passports issued to Taiwanese nationals without household registration — you are not eligible for the VWP at all, and the correct route to the US is a B1/B2 visitor visa processed through AIT in Taipei: a DS-160 form, a $185 government fee and an interview.

Cost, validity and timing

• Government fee: $40 per traveller, paid by card at application. That is the official US charge; anything a preparation service adds is its own fee and should be shown separately.
• Validity: two years, or until your passport expires — whichever comes first — with unlimited entries in that window.
• Stays: up to 90 days per visit, not extendable, and with no switching to work or study status once inside the US.
• Timing: apply at least 72 hours before departure. Most decisions arrive far sooner, but some applications go to manual review, and airlines board only travellers whose ESTA is approved — pending is not enough.

Your name: Wade-Giles, pinyin and the passport biodata page

Taiwanese names have been romanized several ways over the decades — the same surname can appear as Hsu or Xu, Chung or Zhong, Tsai or Cai, and given names are usually hyphenated (MEI-LING). Family members often carry different spellings of the same Chinese name, and many people use an unrelated English first name in daily life. For ESTA, ignore all of that: copy the romanized name from your passport's biodata page exactly — spelling, hyphen and order included. Do not substitute the English name you use at work; it is not the name your passport travels under. And book your flight in the same spelling, because a passport-ESTA-ticket mismatch is the kind of inconsistency that turns check-in into an interrogation.

Using ESTA for a US layover

Plenty of Taiwanese itineraries touch the US only in transit — Taipei to Latin America through Los Angeles, or a connection en route to Canada. The US has no sterile international transit: every passenger clears immigration, even for a one-hour connection, so you need an approved ESTA for a layover just as you would for a holiday. The application lets you declare that you are in transit; the eligibility rules, the fee and the 72-hour guidance are identical. The good news: the same two-year ESTA then covers your future US trips as well.

Two years, many entries — the mechanics

One approved ESTA covers unlimited trips while it is valid. The details that catch people out: renewing your passport cancels the ESTA — it is bound to the passport number, so a new passport always means a new application, even if the old ESTA had a year left; the 90-day ceiling applies per visit, but chaining long stays back-to-back invites questions at the border; and if you already have a valid ESTA from a previous trip, check it on the official CBP site rather than paying for a duplicate.

When Taiwanese travellers need a real visa instead

ESTA is only for short visits. You need an actual US visa if you plan to stay longer than 90 days, work, study, or if your passport lacks a National ID number, if a previous ESTA or visa application was refused, or if you answer “yes” to the security questions honestly — and honestly is the only way to answer them, since a false answer discovered later can bar you from the US for years. In those cases the B1/B2 visitor visa via AIT is the workable route. Unsure where your trip lands? Our free visa checker tells you in seconds, and the Taiwan-to-US requirements page summarises the whole picture.

Approval lets you board — entry is decided at the border

An approved ESTA authorises you to travel to the United States; it does not oblige the US to admit you. The Customs and Border Protection officer at your port of entry makes the final call and may ask about your plans, funds and onward ticket. That is standard for every traveller — see Does ESTA guarantee entry? for how to be sensibly prepared.

Checklist before you fly

• Biometric Taiwan e-passport with your National ID number on the biodata page.
• ESTA approved — not pending — for every traveller, including children, and linked to your current passport.
• Name on the ticket matches the passport romanization exactly, hyphen included.
• Trip (or layover) is 90 days or less, with no work or study planned.
