Certification of Data

What Is Certified Data?

Most states require records that are submitted as evidence in a court of law to be authenticated in some way. To accommodate this requirement, NCEI offers Department of Commerce certification of the data maintained in our archives, which can be ordered online.

If the receiving party is a courthouse or subpoena record room, NCEI requires an immediate fax to 1-828-271-4876, including accompanying subpoena, address confirmation, and order number (order number is obtained upon submission of the order). Without that information, your certified data may be rejected by the recipient and returned to NCEI.

How Much Does Certified Data Cost?

The number of pages determines the cost of certified data, and each order has a $8.00 shipping charge. The table below provides a sample of costs by page range for online orders and reflects a discount of about 15% compared to an order for the same certifications offline. The certification of products ordered through the Climate Data Online system also includes an additional paper copy charge of $3.00 per order.

Number of Pages Cost Shipping Charge Total
0 to 40 $116.00 $8.00 $124.00
41 to 80 $232.00 $8.00 $240.00
