But numbers can change (lapses of mergers), is website would be best as card info can become stale over time —and enterprising outfits could scoop up that number.
They could, but I just tried calling the numbers on the back of two cards from merged/acquired banks and they both forwarded to the acquiring bank. Yes it's a small sample size, but I suspect that there's enough money on the line and enough legacy contracts and systems that banks keep their communication channels active for some time.

How long are bank cards valid? I'd say they expire within 5 years? Also, if there is a merger, wouldn't they send you a new card with updated branding?
Credit cards typically expire after some number of years, and mergers will typically include those phone numbers. If for some reason the acquiring company decides it wants to sunset its acquired phone numbers, it just needs to do so after the expiration date for the last card issued with that number still printed.
