Verification upon arrival would be a driver's license or some other photo ID.  Did you mean for a reference?  If so, it gets sticky.  A lot of guys do not like giving out work numbers.

I have no problem giving out my work phone + cell phone (and hotel phone if I am currently residing in one) and showing you my DL + 1 credit card (to crossref the name)

I would be reluctant to give you my home phone/address, W2 form, tax documents, etc.

I would be comfortable with giving you my work and cell number and my work info if necessary and 1 or 2 refs.

I do not have a problem giving out work info as that is probably the most used verification and a cell phone and a e-mail addy just for hobby use only as pay as you go phones and e-mails are easy to set up and toss away. For arrival verification, I would normally use a passport rather than a DL as my DL has a bit too much personal info I rather not share more than I have to.  Of course, I will not giveout work info until I reserach a provider and I feel some comfort.

Joining a service like "Preferred 411", or one other ones, usually bypasses a lot of the verification problems.

Thank you Jazz

I was hoping that it just slipped past you.
