Inspect the guitar’s body for brand markings and serial numbers. Check hollow body models for a label inside the soundbox that can be viewed and read through the sound hole(s), or numbers engraved on the neck, head or fingerboard. Look on the head and back of the guitar for electric models which often have an engraved plate. Unfortunately, our records are not complete enough to provide precise dating information for many Fender acoustic guitars from the early 1960s through the 1970s and 1980s. Although the tables below are as accurate as possible, serial numbers of these acoustic guitars have never been archived and are of no assistance when attempting to date.

For example, I just checked my Eastman acoustic guitars - listed in the order purchased, year matches the certificate date:
E40D (2016) is 1465xxxx
E40OM (2017) is 1375xxxx
ACTG1 (2017) is 1655xxxx
E20OMSB (2017) is 1365xxxx
E20D (2017) is 1375xxxx
E40D (2017) is 1375xxxx
With the exception of the travel guitar, all of the SN begin with 13 or 14. But of those, my oldest guitar has the highest SN (1465xxxx). I'll edit this post later with exact certificate dates. The third digit *almost* ties to the year --- if I assume the E20OM was assigned in 2016, but not given a certificate until April 2017 (and again, the travel guitar outlier).
If others want to post their model, SN#, and certificate date here... then maybe we can figure out a pattern. In the meantime, maybe I'll email Eastman for more insight. I'll find that UBGF post and copy the contents here for easy reference.
Also, I posted this in the Acoustic section b/c I don't own any Eastman electric guitars (yet!) to confirm if the SN batches are the same. We can move this to General Chatter, if we want to tackle electric SNs here, as well.
