Which information is required for customer identification in travel services?

Customer identification is critical in the travel services industry for several reasons, including compliance with regulations and ensuring the safety and security of transactions. Collecting the name and address of both the person purchasing the service and the person traveling helps verify identities and mitigate risks such as fraud or identity theft.

Having both pieces of information, the name and address, provides a complete profile of individuals involved in the transaction. This is particularly important in scenarios where the traveler may not be the person making the purchase; for instance, when someone is booking a trip for a family member or friend. In such cases, knowing both the purchaser and traveler's details strengthens the verification process.

The other choices, such as only providing the agency's address or just the travel agent's contact details, fall short of ensuring accurate customer identification, as they do not involve the key individuals necessary for accountability and validation within the transaction. Names of previous travelers also do not contribute to identifying current customers and do not fulfill the requirements for identification in travel services.
