Definition
Meaning
A small, durable marker, often made of metal or plastic, attached to a person or item to display essential identifying information, particularly used by military personnel.
Any label, badge, or token attached to or associated with a person, animal, or object to establish its identity, purpose, or ownership. In a technological context, it can refer to a digital marker or token used for system authentication.
Linguistics
Semantic Notes
Primarily associated with military 'dog tags' but has expanded to medical alert tags, pet ID tags, and asset management tags. The phrase implies a physical object rather than a digital process.
Dialectal Variation
British vs American Usage
Differences
In British English, 'identification disc' is a historical alternative, and 'dog tag' is widely understood as the military equivalent. In American English, 'dog tag' is the dominant colloquial term for a military identification tag.
Connotations
In both varieties, strongly connotes military use or serious formal identification (medical, emergency services).
Frequency
More frequent in American English due to higher cultural prominence of military 'dog tags'. In British English, 'ID tag' or 'name tag' might be used in non-military contexts.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation as 'идентификационный ярлык' in non-technical contexts; for pets, use 'бирка' or 'жетон'; for military, 'солдатский жетон' or 'медальон'. The English term is more specific than the general Russian 'опознавательный знак'.
Common Mistakes
- Using 'identification tag' for a simple name badge at a conference (overly formal/technical). Confusing it with 'wristband' or 'pass'. Incorrect plural: 'identifications tags'. Using 'identification' as an adjective without the '-al' suffix (e.g., 'identification tag' is correct, not 'identify tag').

FAQ
Frequently Asked Questions
In military contexts, yes, 'dog tag' is the common colloquial term for a soldier's identification tag. However, 'identification tag' is broader and can refer to medical alerts, pet IDs, or asset tags.
Traditionally, it refers to a physical object. In modern technical contexts (IT, logistics), it can metaphorically refer to a digital identifier, but phrases like 'ID token', 'digital ID', or 'asset tag' are more precise for non-physical markers.
Usually includes the service member's last name, first initial, service number or social security number, blood type, and religious preference.
Using it for casual name badges (e.g., at a party). It sounds overly formal and technical in that context. 'Name badge' or simply 'badge' is more appropriate.
