A rate code is the number that tells the taxi meter, and TLC's trip records, which fare rule is in use for a trip. On the meter screen it appears as a message such as "Rate #01 – Standard City Rate." In TLC data it is the RatecodeID field, "the final rate code in effect at the end of the trip" (yellow data dictionary). The wrong rate code means the wrong fare, so check it at the start of every trip.
The codes
TLC's fare page gives the exact screen wording for Rates #01, #04 and #05. For Rate #04 it adds that "a message should appear on screen alerting the passenger of the rate change."
Check it before you start
Look at the rate message before you start the meter. On a normal city trip it must say Rate #01. On a JFK–Manhattan trip, "the Taximeter must reflect that this trip is a Flat Rate fare" (Rule 58-26(b)(1)(iii)). For Westchester or Nassau, the meter stays on Rate #01 inside the city and switches to Rate #04 only at the City limit.
What the data shows
By our count, 31.5 million yellow trips used the standard rate, 1.1 million the JFK flat fare, 425,596 a negotiated fare, 141,366 Newark and 105,104 Nassau or Westchester. A large block of trips has no rate code. Most of these are Flex Fare trips, where the meter isn't used.
Where drivers see it
- On the meter screen, at the start of the trip and when the rate changes at the City limit.
- On the passenger's receipt, which a rider may use in a complaint.
- In overcharge cases. Charging "double the meter" to a place outside Nassau and Westchester is not allowed. Rule 80-17(f) requires a flat dollar rate agreed before the trip, and says "'double the meter' is NOT a flat rate."
- In TLC data and reports such as the parts of a NYC taxi fare.

Frequently asked questions
What should the meter screen say on a normal city trip?
TLC's fare page says the on-screen rate message should read 'Rate #01 – Standard City Rate.'
When does the meter switch to Rate #04?
When the taxi goes beyond the City limit to Nassau or Westchester. The screen should read 'Rate #04 – Out of City Rate to Nassau or Westchester,' a message should alert the passenger, and the meter charges double from the City limit to the destination.
What is rate code 6?
In TLC's yellow trip data dictionary, RatecodeID 6 means 'Group ride.' It is very rare: 33 yellow trips in Sep 2025 – Aug 2026 by our count.
Why do so many trips have no rate code in the data?
Most rows with a blank rate code are Flex Fare trips (payment type 0), which are priced upfront in an e-hail app instead of on the meter.
