Word of Recall is a 6th level Cleric spell that states
You (...) teleport to a previously designated sanctuary.
It defines this sanctuary as

The text of the spell says nothing about interplanar travel, however we have other spells to look at for reference:
- Teleportation Circle is a 5th level spell that opens a short-lived portal to a predetermined prepared location on the same plane of existence;
- Teleport is a 7th level spell that doesn't allow planar travel, and can be inaccurate depending on the caster's familiarity with the target location;
