FAQ (Frequently Asked Questions):

Have an update to our FAQ? E-mail us.

What do I need to do?
Hand print your name and address (and answer to the math super trivia quiz for those in Canada) on a 3"x5" index card. Throw that in a #10 envelope. Address it to one of the addresses (DO NOT include anything in ()'s that says note:) above, slap first class postage on it(stamp, machine, whatever), and mail it off.
What is NPN? What does NPN stand for? Etc, etc.
NPN means No Purchase Necessary. Basically, you don't have to buy a pack of a particular product product to have a chance to get one of their insert cards (GU, non-GU, Autos, etc)
Why do companies offer NPN?
The main thought on this is that card companies offer NPNs to prevent any legal issues with gambling laws. As far as I know, this is true, but I don't have any documentation/proof of it.
What is #10 envelope?
It's a business size (4-1/8" x 9-1/2") envelope. It's the rectangular one you get most of your mail in (excluding credit card and some utility bills.)
What's a 3x5 index card?
They're note cards. They come in lined, unlined, and many color varieties. The cheapest are the white kind, but I'm sure Topps could care less what color they are.
Where can I get a 3x5 index card, #10 envelope, and a stamp?
The first two, any grocery, drug, or retail store carries them in the office supply stationery section. You usually can get stamps at the same places; if not, go to the post office.
Can I put 2 index cards in one envelope?
No, one index card per envelope.

What's different about Upper Deck?
Update 2/3/08 -
Looks like Upper Deck's NPN website is up in full swing now. They posted 3 new NPNs to the site this past week. I will continue to update this site as they post new NPNs. One important note to make about UD's new rules. It is now 1 entry per person, so nore more multiple entries for UD products.

Update 1/20/08 - After posting on their site that NPNs wouldn't be added until after 1/21, Upper Deck added what appears to be a test NPN, World of Warcraft Feast of the Winter Veil. I filled it out, who knows worth a shot I suppose. Let's hope the sports cards get added this coming week.

Update 1/13/08 - The site if up, sort of. Last week http://sports.upperdeck.com/npn, which is what npn.upperdeck.com forwards to, became active. However, there is a note stating NPNs will only be accepted for products released after 1/21/08.

So, despite Exquisite Rookeis Baseball stating on the pack to goto the website it appears Upper Deck will not be honoring those NPNs.

To redeem NPNs on the website you will need to create an account, if you haven't done so for redemptions in the past you can go there now to create an account to be ready when products do get posted.

Due to UDs statement on their site, I have moved all Upper Deck NPNs to the expired section as it appears no past NPNs will be honored. I will continue to Post active Upper Deck NPNs to this site as they are added to npn.upperdeck.com.

Update 1/6/08 - As everyone can plainly see the new npn.upperdeck.com website is not up and running yet as promised on 1/1/08. Who put the redemption team in charge of website launches? :)

Some minor good news however. I did read tonight someone recieved and e-mail from UD stating they expected the site to launch this Monday now. We will see...

Breaking News: Upper Deck NPNs to go online 1/1/2008! (Mail-in NPNs no longer accepted as of 12/1/07)

Upper Deck begin sending letters to customer this week informing of their new NPN policy. For a copy of the letter, click here. The big news coming from the letter is Upper Deck will be accepting NPN requests via a website starting 1/1/2008. The letter also states Upper Deck will no long accept mail-in requests after 12/1/2007. It appears Upper Deck will not be accepting any NPN requests during the month of December. Starting 1/1/2008 you can got to http://npn.upperdeck.com to submit an NPN request. As of this writing the website is not active.

If I send in, will I always get something back?
Not necessarily. You have the same chance of getting something as if you had opened a pack. So if a Game Used card comes 1:28 packs, you have a 1:28 shot per index card you send in of getting a Game Used card.
It's still unclear on how it works for packs with 1 GU/Auto per pack. Back a couple of years ago, for Topps Tribute, many people got back an Auto or GU for each index card. Recently (specifically thinking of high end UD stuff), some companies specify that the NPN drawing is for everything but the 1 per pack items.
Also, remember the companies don't have an unlimited supply of cards set back for NPNs. If they get far more requests than expected, likely that reduces your chances of getting something back. Although, the packs do say "At the same odds" without mentioning number of requests.
What if I don't use a #10 envelope? What if my index card is 5" x 7"? What if I write in crayon? etc, etc
The card companies measures all index cards and envelopes for the appropriate size before validating your entry. JUST KIDDING. The answer is, I don't know. I saw someone post on the Beckett message boards that they used smaller envelopes to mail in entries, and they still got free cards. So, use "non-standard NPN" materials at your own risk. But as long as the stuff gets there, I doubt the card companies really care about the exact materials. Of everything though, I'd reccomend using 3"x5" cards; that's what they use for the drawing, so it's the most important.
What happens if I send in more allowed number of entries?
The card company could disqualify your entries since it's technically a contest, and you're breaking the rules.
Can I send in entries for both the retail and hobby versions of the product?
No. NPNs specify that the limits are for the product overall, not on which version of the product you're mailing in an NPN for.
Can I send in more than 2 entries by using a different name/address?
I don't advocate it. Most NPN's are now 1 or 2 entries per household. Household is defined as "A domestic unit consisting of the members of a family who live together along with nonrelatives such as servants" by Dictionary.com So basically, if you live with 8 other people who collect cards, you have to share two entries. But, I know people use multiple addresses/names, such as their girlfriend, grandma, second cousin twice removed, etc. addresses'. While it's technically a different household, it is for you. Personally, I don't think it's all that ethical, but that's just my personal opinion
Do I have to send in postage or a SASE (Self Addressed Stamped Envelope) for them to send me back my card if I win?
Nope, just the index card. If you win, the card company pays for the postage.
When will I know if I won?
The dates listed above are the "postmark" date, the date you have to have mailed the entries by. Generally the recieved by date (by which the card company has to have received the entries) is one week later. The drawing date is then a week after that. Winning entries (ie the cards) usually show up around a month after the drawing date. The first NPN's that I posted (long ago), had a drawing date of May 7th, and they started arriveing June 6-7, so the month seems pretty accurate.
