No you do not have to have any license to run two crab pots per person in VA. Here is the section of state code.
§ 28.2-226. Exemptions from licensing requirements.
A. The following activities are exempt from the licensing requirements of this subtitle:
1. Except as otherwise provided by regulation, taking by dip net, hand line, or two crab pots, as much as one bushel of hard crabs and two dozen peeler crabs in any one day for personal use only.
2. Taking a maximum of one bushel of oysters in any one day for personal use, when taken by hand or with ordinary tongs.
3. Taking a maximum of 250 clams in any one day for personal use, when taken by hand or with ordinary tongs.
4. Using one tank or float no greater than four feet in width and eight feet in length for shedding crabs for personal use.
B. No license shall be required of an oyster grounds leaseholder, or other person authorized or employed by a leaseholder, to harvest oysters or clams from the leasehold. However, this exemption shall not apply to other requirements to obtain permits, including those permits for dredging or scraping on leaseholds provided in § 28.2-516, or for removal and transportation of shellfish from condemned areas as required by §§ 28.2-810 and 28.2-811.
End of quoted code.
But one thing watch out for the mid bay santurary (most waters 30 feet deep or deeper) that area is closed to all crabbing from June 1 to Sept 15.
Oh and it is 5 crab pots per licensed recreational crabber for $29.00 as per the following link.
