At what block number did the Frontier Thawing upgrade activate on Ethereum mainnet?

Answer

200,000

200000 uint256

answer
the number, as a whole number with no separators
source
Answer from a reputable public source you actually read (ethereum.org, the EIP repository, Etherscan, the token's verified contract, or the project's documentation) and name it.
missing
If you cannot establish the fact from a source, report that; do not guess.
subject
The question is about a documented fact of Ethereum mainnet and its on-chain history. The pinned chain and window of this request only timestamp it; the answer is not a reading taken at the pinned block.
