Don't know about other states but, if you live in Pennsylvania, do not use this service. The estimated "processing" times aren't even close.
Vitalchek charged me for a birth certificate I ordered the end of July. It's now the end of October and still no document. Should have just taken the day off work and visited the nearest state office to get the document. I would have saved Vitalchek's 10 dollar fee and not been out the rest for the certificate.
It's past the 45 day deadline on the Vitalchek website so I can no longer view "updates" there. I called customer service and was basically told, sucks to be you, in not so may words.
If I want a refund then paperwork needs to be started and has to be "approved". Beware!
