身元 and 身分: identity at reception and concealed status
Compare identification at reception with a traveler's unrevealed identity and a character's concealed status. Preserve the overlap in identity meanings without restricting 身分 to social rank.
Identification connected with 身元
「受付で身元を確認できる書類を見せた。」 (I showed identification at reception.)
Another example describes a traveler in a story who never reveals his identity. Showing identification at reception and concealing identity in the story are separate scenes.
Proof of identity and concealed 身分
「受付で身分を証明する書類を見せた。」 (I showed a document proving my identity at the reception desk.)
In a story, the main character travels while concealing their social status. A document proving identity and the concealed status in that fictional scene have different contexts.
Overlapping meanings of identity and status
Both reception examples concern documents connected with identifying a person. 身元 and 身分 are not separated here into identity only and social rank only.
Keep the traveler who never revealed his identity separate from the main character concealing their status. Showing a document does not itself report every reception check completed or establish a particular legal procedure.
Does the 身分 document shown at reception concern only social rank and have no connection with identity?
Show the answer and why
No. The example describes a document proving the person's identity. The identity meanings overlap at reception, while concealed social status belongs to the separate story example.
